Title: Manufacture of vertical-type superlattice
Inventor: KURODA NAOTAKA
IPC: H01L21/20
Filed: 1990-02-06
Abstract: PURPOSE:To obtain a vertical-type superlattice having a steep interface on the order of an atomic layer by a method wherein the surface of a semiconductor substrate is irradiated with a plasma beam, an ion beam or the like at an angle of 45 deg. or lower to the surface of the substrate from a direction of 90 deg. to the off-angle direction of the substrate. CONSTITUTION:When the surface of a semiconductor substrate is irradiated with a plasma beam, an ion beam or a molecular beam at angle of 45 deg. or lower to the substrate, it is possible to etch and flatten uneven parts on the order of an atomic layer on the surface of the semiconductor substrate. In addition, when the substrate is irradiated with the plasma beam from a direction of 90 deg. to the off-angle direction of the substrate, not only the uneven parts on the order of an atomic layer on a terrace are flattened, but also the uneven parts are flattened even at a step and a flat step can be formed on the order of the atomic layer. When a vertical-type superlattice is grown on the off- substrate having the step flattened on the order of the atomic layer, it is possible to obtain the vertical-type superlattice whose interface is steep on the order of the atomic layer.

Filed: 1991-02-22
Abstract: PURPOSE:To prevent deterioration in reception sensitivity by using an output impedance of a mixer circuit in place of an input resistor of a buffer amplifier so as to eliminate thermal noise caused in the input resistor. CONSTITUTION:An output impedance of output circuits 30I, 30Q of mixer circuits 30I, 30Q is nearly equal to collector load resistance R11', R12' because the collector output impedance of transistors(TRs) 13-16 is very high. Moreover, the TRs 13-16 act like a current source when viewing the TRs from a collector terminal. In the equivalent circuit, the relation of R12'=R11' and Z12=Z11 is in existence. In this case, the gain of buffer amplifiers 60I, 60Q is set to a desired value by selecting the Z11, Z12. That is, the buffer amplifiers 60I, 60Q are formed to have a feedback impedance circuit Z11 between an output terminal and an inverted input terminal of an operational amplifier OP and the gain is selected in a ratio of the impedance Z11 to an output impedance of the mixer circuits 30I, 30Q. Through the constitution above, the noise generated in the buffer amplifier is reduced and the reception sensitivity is improved.
